[R.O. 2011 §400.830; Ord. No. 2006-170 §1, 12-19-2006]
A. 
Streets — General Requirements.
1. 
Grading and improvement plan. Streets, including right-of-way, shall be graded and improved and conform to the City of Riverside construction standards and specifications and shall be approved as to design and specifications by the Director of Community Development or their designees in accordance with the required construction plans.
[Ord. No. 1671, 7-16-2019]
2. 
Topography and arrangement.
a. 
All streets shall be properly integrated with the existing and proposed street network. Except for courts and cul-de-sacs, streets shall generally connect with streets already dedicated in adjoining or adjacent developments or provide for future connections to adjoining lands or shall be a reasonable projection of streets in the nearest development.
b. 
The arrangement of major streets in the development shall comply with KCAPWA standards and the Comprehensive Master Plan. Streets shall be properly related to population densities, existing and proposed land use patterns and special traffic generators, such as industries, business districts, schools, churches and shopping centers.
c. 
Streets shall be related appropriately to the topography. A combination of steep grades and curves shall be avoided. All streets shall be arranged so as to obtain as many building sites as possible at or above the grades of the streets.
d. 
Local streets shall be planned in order to conform as much as possible to the topography, to discourage use by through traffic, to permit efficient drainage and utility systems and to require the minimum number of streets necessary to provide convenient and safe access to property.
e. 
In commercial and industrial developments, the streets and other accessways shall be planned in connection with the grouping of buildings, location of rail facilities and the provision of alleys, truck loading and maneuvering areas and walks and parking areas so as to minimize conflict of movement between the various types of traffic, including pedestrian.
3. 
Level of service. The developer shall make provisions so that arterial and collector streets impacted by a development maintain a level of service C or better, when the development is at full occupancy. The developer may be required to submit a traffic impact analysis (TIA) if the proposed development is anticipated to have a material impact on the transportation network within the City. If a TIA shows that a proposed development creates the need for additional off-site right-of-way or other improvements, the developer may be required to provide right-of-way or improvements proportional to the demand created prior to development approval.
4. 
Classification. All streets shall be classified as an arterial, collector, residential collector or local street. Street classification shall be based on the Comprehensive Master Plan and the projected traffic demands.
5. 
Access. There shall be an adequate number of points of ingress to and egress from the development to ensure sound traffic engineering design, smooth traffic flow into and out of all portions of the development and the public's safety. In determining whether the development provides for an adequate number of points of ingress and egress, all relevant factors shall be considered including, but not limited to, the following:
a. 
Residential development. Generally, one (1) point of ingress to and egress from the development should be required for each one hundred (100) dwelling units in the development. Each required point of ingress to and egress from the development shall be located so as to best serve the traffic generated by the development.
b. 
Non-residential development. The adequacy of the number of points of ingress to and egress from non-residential developments shall be determined based on the proposed uses and proposed site layout.
c. 
General factors.
(1) 
Traffic accumulation. The level of traffic using each point of ingress to and egress from the development should not exceed the level of traffic that the street is designed to accommodate.
(2) 
Access for emergency vehicles. The points of ingress to and egress from the development should be adequate to ensure that emergency vehicles can gain access to all proposed uses within the development, whenever necessary.
(3) 
Intersection with streets abutting the development. The impact of injecting traffic from the proposed development into the existing street network shall be mitigated by location, design and control measures consistent with the standards of traffic engineering.
6. 
Street names. To ensure the naming of streets shall be consistent with the City addressing grid system, the street names shall appear on the plat. Proposed street names shall be sufficiently different in sound and spelling from other street names in the City so as not to cause confusion. Streets that are in alignment with already existing and named streets shall bear the names of the existing streets.
7. 
Street signs. The developer shall pay to the City the cost of purchasing and installing street signs at all intersections within or abutting the development. The term "street sign", as used herein, shall include all traffic control signs, street name signs and any other street signage that is to be owned and maintained by the City after installation. All street signs associated with the development shall be installed before any certificates of occupancy shall be issued for the development.
8. 
Street lights. The developer shall be responsible for the purchase and installation of street lights within the development. Street lights shall be installed in accordance with KCAPWA design and specification standards. A street lighting plan shall be submitted to the City for review and approval prior to the installation of any street lights.
9. 
Culs-de-sac/temporary dead-ends.
a. 
Culs-de-sac may be permitted where topography or other conditions justify their use and provisions are made for adequate traffic circulation. Culs-de-sac should not be longer than eight hundred (800) feet measured from the center line of the cul-de-sac to the center line of the connecting street. Exceptions may be made where topography or other conditions justify a longer length. A turnaround shall be provided at the closed end, with a radius of at least forty-eight (48) feet to the back of the curb and a right-of-way radius of not less than fifty-nine (59) feet in accordance with standards of the 2018 International Fire Code.
[Ord. No. 1671, 7-16-2019]
b. 
If the property adjacent to the development is undeveloped and a street must temporarily be a dead-end street, the right-of-way and road improvement shall be extended to the property line. A temporary turnaround shall be constructed with a minimum radius of thirty-five (35) feet. The temporary turnaround shall be constructed of asphaltic concrete with a minimum depth of eight (8) inches. When a temporary turnaround is required, a notation shall be added on the plat indicting that land outside the normal street right-of-way shall revert to abutting property owners whenever the street is continued. The City may limit the length of temporary dead-end streets in order to ensure the public safety and general welfare of the City.
10. 
Private streets. Private streets shall generally not be permitted in any development. Exceptions may be considered in commercial, industrial and mixed use developments, if the streets are constructed in accordance with City standards and are deemed appropriate for the area and proposed development. A special association shall be formed to maintain any private street.
B.

5. 
Extension/oversizing. Upon recommendation of the Director of Commuity Development and the Planning and Zoning Commission, the Board of Aldermen may require that sanitary sewer lines be oversized to accommodate planned development.
[Ord. No. 1671, 7-16-2019]

Section 400.860 Storm Water Management.

[R.O. 2011 §400.860; Ord. No. 2006-170 §1, 12-19-2006]
A. 
General Requirements.
1. 
Unless otherwise specified within these regulations, an adequate drainage system, including pipes, culverts, intersectional drains, drop inlets, bridges and other approved methods for proper drainage of all water, shall be provided for each development. The storm water management system shall be designed and constructed in accordance with the standards of KCAPWA, unless otherwise noted in this Section.
2. 
Storm water systems shall be separate and independent of any sanitary sewer system.
3. 
Unless otherwise specified by the City, storm sewers shall be designed by the Rational Method and a copy of design computations shall be submitted along with construction plans.
4. 
Inlets shall be provided so that surface water is not carried across or around any intersection nor for a distance of more than six hundred (600) feet in the gutter. Provisions shall be made to prevent surface water from flowing onto public right-of-way from a private development at all possible locations. When such provisions are impracticable, computations shall be provided to show assurance that the public system is adequately sized to receive the additional surface water from the development. When calculations indicate that curb capacities are exceeded at a point, no further allowance shall be made for flow beyond that point and catch basins shall be used to intercept flow at that point. Surface water drainage patterns shall be shown for each and every lot and block. Where applicable, an overland flow escape route must be identified and calculations must be provided to verify that no principal structures will be flooded when larger return period storms exceed the capacity of the proposed storm water system.
B. 
Nature Of Storm Water Facilities.
1. 
Location. The developer may be required by the City to construct facilities to convey any spring or surface water that may exist either previously to or as a result of the development. Such drainage facilities shall be located in the road right-of-way, where feasible, or in perpetual unobstructed easements.
2. 
Accessibility to public storm sewers. Where a public storm sewer is accessible, the developer shall install storm sewer facilities or if no outlets are within a reasonable distance, adequate provision shall be made for the disposal of storm water, subject to the specifications of the City. If a connection to a public storm sewer will be provided eventually, the developer shall make arrangements for future storm water disposal by a public utility system. Provision for such connection shall be incorporated by inclusion in the performance bond required for platting. An agreement by the Board of Aldermen for the maintenance of said storm sewers is required or an agreement for such maintenance by a property owners' association is required.
3. 
Accommodation of upstream drainage areas. A culvert or other drainage facility shall in each case be large enough to accommodate potential runoff from its entire upstream drainage area, whether inside or outside the development. The developer shall determine the necessary size of the facility, assuming conditions of maximum potential watershed development permitted by this Chapter. Such determination shall be verified and approved by the City.
4. 
Effect on downstream drainage areas. The developer shall determine the effect of the development on existing downstream drainage facilities outside the area of the development. Such determination shall be verified and approved by the City. Drainage studies, together with such other studies as shall be appropriate, shall serve as a guide to needed improvements. Where it is anticipated that the additional runoff incident to the development will overload an existing downstream drainage facility, the City may withhold approval of the development until provision has been made for the expansion of the existing downstream drainage facility. No development shall be approved unless adequate drainage will be provided to an adequate downstream drainage watercourse or facility.
5. 
Areas of poor drainage. When development is proposed for an area that is subject to flooding, the City may approve such application provided that the developer fills the affected area to an elevation sufficient to place the elevation of streets and lots at a minimum of twenty-four (24) inches above the elevation of the 100-year floodplain. A copy of the required floodplain fill permit shall be submitted prior to the issuance of a building permit, along with computations showing that the elevation requirements have been met. The development shall provide for an overflow zone along the bank of any stream or watercourse in a width that shall be sufficient to contain or move the water in times of high water. No fill shall be placed in the overflow zone nor shall any structure be erected or placed in the overflow zone. The boundaries of the overflow zone shall be subject to approval by the City. Development of areas of extremely poor drainage is discouraged and the City may deny development in such areas.
6. 
Floodplain areas. The City may, when it deems it necessary for the health, safety or welfare of the present and future population of the area and necessary to the conservation of water, drainage and sanitary facilities, prohibit the development of any portion of the property that lies within the floodplain of any stream or drainage course. These floodplain areas shall be preserved from any and all destruction or damage resulting from clearing, grading or dumping of earth, waste material or stumps, except at the discretion of the City.
7. 
Best management practices (BMP). The storm water management system shall follow BMP requirements of the City. The City may deny any development applications that do not incorporate such practices.
C. 
Dedication Of Drainage Easements.
1. 
General requirements. When a development is traversed by a watercourse, drainageway, channel or stream, there shall be provided a storm water easement or drainage right-of-way conforming substantially to the lines of such watercourse and of such width and construction as will be adequate for the purpose. Wherever possible, drainage should be maintained by an open channel with landscape banks and adequate width for maximum potential volume of flow.
2. 
Drainage easements.
a. 
Where topography or other conditions are such that it is impractical to include drainage facilities within street right-of-way, perpetual, unobstructed easements at least fifteen (15) feet in width for drainage facilities shall be provided across property outside the road lines and with satisfactory access to the road. Easements shall be indicated on the plat. Drainage easements shall extend from the road to a natural watercourse or to other drainage facilities.
b. 
When a proposed drainage system will carry water across private land outside the development, appropriate drainage rights must be secured and indicated on the plat.
c. 
The developer shall dedicate, either in fee simple title or by a drainage or conservation easement, land on both sides of existing watercourses to a distance to be determined by the City.
d. 
Low-lying land along watercourses subject to flooding or overflowing during storm periods, whether or not included in areas for dedication, shall be preserved and retained in their natural state as drainageways.

Section 400.870 Utilities and Easements.

[R.O. 2011 §400.870; Ord. No. 2006-170 §1, 12-19-2006]
A. 
Location. All utility facilities including, but not limited to, gas, electric, telephone and cable shall be located underground throughout the development. Whenever existing utility facilities are located above ground, except where existing on public roads and right-of-way, they shall be removed and placed underground. All utility facilities existing and proposed throughout the development shall be shown on the plat.
B. 
Easements.
1. 
An easement at least ten (10) feet wide shall be provided for utilities along each side or rear line of a lot. The width of the easement shall also account for unusual topography or for easements needed for multiple utilities to ensure the proper placement and maintenance of utility lines.
2. 
Except where prohibited by topography, utility easements shall be located on lot lines in the rights-of-way of streets or in separate utility easements. The City may require all easements for drainage or sewer to be selectively cleared of undergrowth, trees and other obstructions by the developer.
3. 
Utility easements shall connect with easements established in adjoining properties.
4. 
Utility easements shall be shown on the plat and dedicated in conjunction with recordation of the final plat.
